YOUNG FREMONT BLACK, OF MAXVILLE, INDIANA.

CAR-COUPLING.

SPECIFICATION forming part of LettersPatent No. 301,792, dated July 8, 1884.

Application filed May mesh, (No intact) To all whom, it may concern Be it known that I, YOUNG FREMONT BLACK, a citizen of the United States, residing at Maxville, in the county of Vigo and State of Indiana, have invented a new and useful Gar-Coupling, of which thefollowing is a specification, reference being had to the accompanying drawings.

This invention has relation to car-coup lings; and it consists in the construction and novel arrangementof parts, as will be hereinafter fully described, and particularly pointed out in the claims.

Figure 1 is a view in perspective of a carcoupling embodying my improvements. Fig. 2 is a horizontal section on the liner min Fig. 1, and Fig. 3 is a vertical longitudinal section on theline g g in Fig. 1. Fig. 4 is a bottom View of the coupling-bar.

Referring by letter to the accompanying drawings, A designates the car-body, and B the draw-head of the car-coupling, which is secured to the timbers of the car in any suitable manner. This draw-head is rectangular in shape, and is made in two sections-an upper section, 0, and a lower section, D, bolted together near their forward ends by bolts E E, which form the fulcrums for the pivoted coupling-levers F F, and also connected together at their rear ends in any suitable manner. The upper section, 0, is provided with the mouth G for the draw-head, and also with a slot, H, in its upper wall, through which the upper end of the bifurcated anglearm I extends. The coupling-levers F'F are provided with shoulders on their upper faces near their forward ends, which engage rectangular blocks J J 011 the bolts E E above them.. The rear ends of the coupling-levers F F are provided with vertical projections K K, which are connected with the blocks J J by fiat springs L L, the function of which is to throw the coupling-levers inwardly after the head of the coupling-bar passes their inner ends, where they are locked in the coupling position. The blocks J J are provided with laterally-extended arms M M, which are pivoted to each other and t0 the bifurcated angle-arm I.

To the upper end of the angle-arm I is pivoted the forward end of a bifurcated arm, N, the rear end of which is connected to the inner end of a crank-shaft, 0, having a bear ing, 1, on the upper face of the draw-head,

and abearing, P, secured to the end of the car-body A. The bearing 1? is provided with a rack, Q, with two notches, R and S, for the lever T onv the outer end of the crank-shaft. The lever operates the crankshaft, and throughthis shaft and its connections the coupling-levers are operated. WVhen the leverT. is in the'rear notch, R, the couplinglevers are spread apart in the draw-head, and the arrow-shaped head of the coupling-bar U will not engage the coupling-levers when entered into the draw-head. When the lever T occupies the notch S, the coupling-levers will be in the position shown in Fig. 2, and will engage the arrow-head of the coupling-bar and couple the cars. The lower section of the draw-head is provided on its upper face with a guide stud, V, which engages the groove in the under face of the coupling-bar, and guides it to place when it enters the drawhead. By arranging the car-couplings in this manner it is unnecessary to enter between the cars to couple or uncouple them. When set for coupling, the device couples automatically, and to uncouple it is only necessary to pull the lever T to the rear notch, R, of the rack.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. The combination,with the section 0 of the draw-head, provided with the mouth G and slot H, and the section D, secured thereto by bolts E E, and arear connection, of the coupling-levers F F, having shoulders at their forward ends, and projections K K at their rear ends, the blocks J J, having arms M M, angle-arm I, springs L-L, arm N, crank-shaft O, lever T, bearings P P, and notchedrack Q,

substantially as specified.

2.. The combination, with the draw-head provided with the guide-stud V on the upper face of the lower section, and the pivoted coupling-levers and mechanism, substantially as described, for operating them, of the coupling-bar having grooves in its under facefto engage the guide-stud, substantially as specified.

In testimony that I claim the foregoing as my own I have'hereto affixed' my signature in presence of two witnesses.
